ObjectArx的一次常用方法
1.画一条直线
static void ArxProject1_DrawLine(void) { // Add your code for command ArxProject1._DrawLine here //创建一条直线 AcGePoint3d ptStart( 0 , 0 , 0); AcGePoint3d ptEnd( 100 , 100 , 0); AcDbLine* lnNew = new AcDbLine( ptStart , ptEnd); AcDbBlockTable* pBlockTable = NULL; acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForWrite); AcDbBlockTableRecord* pBlockTableRecord = NULL; pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord , AcDb::kForWrite); AcDbObjectId lnId; pBlockTableRecord->appendAcDbEntity( lnId , lnNew); lnNew->close(); pBlockTableRecord->close(); pBlockTable->close(); }
2.画一段圆弧
static void ArxProject1_DrawArc(void) { //三点创建一个圆弧 AcGePoint2d ptStartPoint( 0 , 100 ); AcGePoint2d ptEndPoint( 0 , 100 ); AcGePoint2d ptCenterPoint(0 , 0); AcGeVector2d vecStart(ptStartPoint.x - ptCenterPoint.x , ptStartPoint.y - ptCenterPoint.y); AcGeVector2d vecEnd(ptEndPoint.x - ptCenterPoint.x , ptEndPoint.y - ptCenterPoint.y); double StartAng = vecStart.angle(); double EndAng = vecEnd.angle(); AcGePoint3d pt( 0 , 0, 0); AcGeVector3d vec( 0 , 0 ,1); AcDbArc* Acr = NULL; Acr = new AcDbArc(pt ,vec , 100, StartAng , EndAng); AcDbBlockTable* pBlockTable = NULL; ErrorStatus es = acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForWrite); AcDbBlockTableRecord* pBlockTableRecord = NULL; es = pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord, AcDb::kForWrite); AcDbObjectId oid; es = pBlockTableRecord->appendAcDbEntity(oid , Acr); Acr->close(); pBlockTableRecord->close(); pBlockTable->close(); }
3.创建一个块，并把它插入到当前的模型空间
static void ArxProject1_CreateNewBlock(void) { // Add your code for command ArxProject1._CreateNewBlock here ErrorStatus es ; AcDbBlockTable* pBlockTable = NULL; acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForWrite); AcDbBlockTableRecord* pBlockTableRecord = new AcDbBlockTableRecord(); pBlockTableRecord->setName(_T("Hest")); AcDbObjectId BlockTableOid; pBlockTable->add(BlockTableOid , pBlockTableRecord); AcDbPolyline* pPloyLine= new AcDbPolyline(); AcGePoint2d pt1(0 , 0); AcGePoint2d pt2(100,200); pPloyLine->addVertexAt( 0 , pt1);; pPloyLine->addVertexAt( 1 , pt2); AcDbObjectId oid; pBlockTableRecord->appendAcDbEntity(oid , pPloyLine); pPloyLine->close(); pBlockTableRecord->close(); pBlockTable->close(); } // - ArxProject1._BlockInsert command (do not rename) static void ArxProject1_BlockInsert(void) { // Add your code for command ArxProject1._BlockInsert here AcDbBlockTable* pBlockTable = NULL; acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForRead); if (!pBlockTable->has(_T("Hest"))) { acutPrintf(_T("不存在块Hest")); pBlockTable->close(); return; } ads_point pt; if (acedGetPoint( NULL , _T("\n请输入插入点") , pt) != RTNORM) { pBlockTable->close(); return; } AcGePosition3d pt3d = asPnt3d(pt); AcDbObjectId oid; pBlockTable->getAt(_T("Hest") , oid ); AcDbBlockReference* pBlockRef = new AcDbBlockReference( pt3d , oid); AcDbBlockTableRecord* pBlockTableRecord = NULL; pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord , AcDb::kForWrite); AcDbObjectId refid; pBlockTableRecord->appendAcDbEntity(refid , pBlockRef); pBlockRef->close(); pBlockTableRecord->close(); pBlockTable->close(); }
4.创建一个新的图层
static void ArxProject1_CreateNewBlock(void) { // Add your code for command ArxProject1._CreateNewBlock here ErrorStatus es ; AcDbBlockTable* pBlockTable = NULL; acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForWrite); AcDbBlockTableRecord* pBlockTableRecord = new AcDbBlockTableRecord(); pBlockTableRecord->setName(_T("Hest")); AcDbObjectId BlockTableOid; pBlockTable->add(BlockTableOid , pBlockTableRecord); AcDbPolyline* pPloyLine= new AcDbPolyline(); AcGePoint2d pt1(0 , 0); AcGePoint2d pt2(100,200); pPloyLine->addVertexAt( 0 , pt1);; pPloyLine->addVertexAt( 1 , pt2); AcDbObjectId oid; pBlockTableRecord->appendAcDbEntity(oid , pPloyLine); pPloyLine->close(); pBlockTableRecord->close(); pBlockTable->close(); } // - ArxProject1._BlockInsert command (do not rename) static void ArxProject1_BlockInsert(void) { // Add your code for command ArxProject1._BlockInsert here AcDbBlockTable* pBlockTable = NULL; acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable , AcDb::kForRead); if (!pBlockTable->has(_T("Hest"))) { acutPrintf(_T("不存在块Hest")); pBlockTable->close(); return; } ads_point pt; if (acedGetPoint( NULL , _T("\n请输入插入点") , pt) != RTNORM) { pBlockTable->close(); return; } AcGePosition3d pt3d = asPnt3d(pt); AcDbObjectId oid; pBlockTable->getAt(_T("Hest") , oid ); AcDbBlockReference* pBlockRef = new AcDbBlockReference( pt3d , oid); AcDbBlockTableRecord* pBlockTableRecord = NULL; pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord , AcDb::kForWrite); AcDbObjectId refid; pBlockTableRecord->appendAcDbEntity(refid , pBlockRef); pBlockRef->close(); pBlockTableRecord->close(); pBlockTable->close(); }
5.插入一个外部的dwg文件，以块的方式
static void ArxProject1_InsertDwg(void) { // Add your code for command ArxProject1._InsertDwgB here AcDbDatabase* pNewDb = new AcDbDatabase(Adesk::kFalse); AcApDocument* pcurDoc = NULL; pcurDoc = curDoc(); if (pcurDoc == NULL) { assert(FALSE); return; } acDocManager->lockDocument(pcurDoc); Acad::ErrorStatus es; es = pNewDb->readDwgFile(_T("D://测试数据//528500-2524250-250-250.dwg") , _SH_DENYNO , FALSE); if (es != ErrorStatus::eOk) { acutPrintf(_T("Read Dwg fail")); return ; } AcDbDatabase* pCurDb = acdbHostApplicationServices()->workingDatabase(); AcDbObjectId oid; es = pCurDb->insert(oid , _T("InsertDwg") , pNewDb ,true); if (es != ErrorStatus::eOk) { assert(FALSE); return; } AcDbBlockReference* pRef = new AcDbBlockReference(); pRef->setBlockTableRecord(oid); AcDbBlockTable* pBolck = NULL; pCurDb->getBlockTable(pBolck , AcDb::kForWrite); AcDbBlockTableRecord* pBolckRecord = NULL; pBolck->getAt(ACDB_MODEL_SPACE , pBolckRecord , AcDb::kForWrite); AcDbObjectId refid; pBolckRecord->appendAcDbEntity(refid , pRef); pRef->close(); pRef = NULL; pBolck->close(); pBolck = NULL; pBolckRecord->close(); pBolckRecord = NULL; acDocManager->unlockDocument(pcurDoc); }
6.插入一张图片作为外部参照
static void ArxProject1_InsertImg(void) { CString strImgPath = _T("C:\\opencv\\samples\\cpp\\tutorial_code\\images\\yellowball.jpg"); AcDbObjectId oid; //insertIMGFile( oid , _T("0") , strImgPath , _T("yellowball") , AcGePoint2d( 0 , 0 ) , AcGePoint2d( 100 , 100)); InsPic(strImgPath); return ; } static bool InsPic(CString strPath) { #if _MSC_VER >= 1600 if (!acrxDynamicLinker->loadModule(_T("acISMobj19.dbx"), true)) { acutPrintf(_T("无法加载acISMobj19.dbx\n")); } #elif _MSC_VER >= 1500 if (!acrxDynamicLinker->loadModule(_T("acISMobj18.dbx"), true)) { acutPrintf(_T("无法加载acISMobj18.dbx\n")); } #elif _MSC_VER >= 1400 //一定要加载此文件，否则加载影像图时会失败 if (!acrxDynamicLinker->loadModule(_T("acISMobj17.dbx"), true)) { acutPrintf(_T("无法加载acISMobj17.dbx\n")); } #elif _MSC_VER >= 1300 if (!acrxDynamicLinker->loadModule(_T("acISMobj16.dbx"), true)) { acutPrintf(_T("无法加载acISMobj16.dbx\n")); } #else if (!acrxDynamicLinker->loadModule(_T("acISMobj15.dbx"), true)) { acutPrintf(_T("无法加载acISMobj15.dbx\n")); } #endif AcDbObjectId imgDicId = AcDbRasterImageDef::imageDictionary(acdbHostApplicationServices() ->workingDatabase()); Acad::ErrorStatus es; if (imgDicId.isNull()) { es = AcDbRasterImageDef::createImageDictionary(acdbHostApplicationServices() ->workingDatabase(), imgDicId); } AcDbDictionary *pDic = NULL; es = acdbOpenObject((AcDbObject*&)pDic, imgDicId, AcDb::kForWrite); AcDbRasterImageDef *pImgDef = new AcDbRasterImageDef; es = pImgDef->setSourceFileName(strPath); es = pImgDef->load(); CString strImg; es = AcDbRasterImageDef::suggestName(pDic, strPath, strImg.GetBuffer(256)); AcDbObjectId entId; bool bHas = pDic->has(strImg); if (!bHas) { es = pDic->setAt(strImg, pImgDef, entId); } else { pDic->close(); delete pImgDef; return false; } pDic->close(); pImgDef->close(); AcDbRasterImage *pImg = new AcDbRasterImage; AcGeVector3d uVec,vVec; uVec.set(50, 0,0); uVec.set(0, 150, 0); AcGePoint3d pt(100, 100, 0); BOOL bSet = pImg->setOrientation(pt, uVec, vVec); pImg->setFade(5); pImg->setContrast(9); es = pImg->setImageDefId(entId); AcDbBlockTable* pBlockTable = NULL; es = acdbHostApplicationServices()->workingDatabase()->getBlockTable( pBlockTable , AcDb::kForWrite); if(es != ErrorStatus::eOk) return FALSE; AcDbBlockTableRecord* pBlockTableRecord = NULL; es = pBlockTable->getAt(ACDB_MODEL_SPACE , pBlockTableRecord , AcDb::kForWrite); if(es != ErrorStatus::eOk) return false; AcDbObjectId oid; es = pBlockTableRecord->appendAcDbEntity(oid , pImg); if(es != ErrorStatus::eOk) return false; AcDbObjectId entIdx = pImg->objectId(); pImg->close(); return true;}
7.插入dwg作为外部参照
static void ArxProject1_Addxref(void) { // Add your code for command ArxProject1._Addxref here AcDbObjectId oid; ACHAR lpszBlockName[255]; ACHAR* lpszFileName = _T("C:\\XREGER.dwg"); ErrorStatus es = acedXrefAttach( lpszFileName , lpszBlockName); if (es != ErrorStatus::eOk) { acutPrintf(_T("添加Xref失败!\n")); } }
